How do I connect Fathom to Slashy?

Press Cmd and comma to open Settings, choose Integrations in the sidebar, then Meeting Notes, then click Fathom. Click Connect Fathom and sign in with the Fathom account that records your meetings. Authorization runs through OAuth, so Slashy receives read access to your meetings. After Fathom confirms access you are redirected back and the integration page shows Connected.

What does the Fathom integration put on a calendar event?

Three things: the meeting summary, the transcript, and any action items Fathom captured. They attach to the matching calendar event and appear in the event detail panel under a Fathom section that expands to the full transcript and action item list.

Can I ask about a past call instead of reading the transcript?

Yes. Press Cmd and slash and ask the agent something like "What did we agree with Acme last week?". It searches your connected meeting notes and returns an inline card with the meeting, the date, the participants, and a link to the recording.

What happens to my meeting data if I disconnect Fathom?

Slashy stops pulling new recordings and also removes the existing Fathom data from your events. Your data inside Fathom itself is untouched. Worth knowing before you trial it, because the copy on your calendar goes with the connection.

Is it safe to give Slashy access to my Fathom transcripts?

Slashy is SOC 2 Type II and CASA Tier 2 certified, encrypts data at rest with AES-256 and uses TLS 1.2 or higher in transit. Slashy does not train AI models on your email or meeting data, and its AI providers operate under zero data retention. The Fathom connection itself is read-only.

Fathom Email Integration: Put Call Recordings on Your Calendar

Q: Why has a recording not attached to the right meeting?

Slashy matches a Fathom recording to a calendar event when both fall in a similar start window. If you record a session with no calendar invite, Slashy keeps it in your Fathom list but does not attach it to an event. If a recording landed on the wrong meeting, open the event, click the Fathom section, and reassign from the dropdown of nearby recordings.

Connect Fathom to Slashy so the summary, transcript and action items from each recorded call attach to the matching calendar event before you write back.

Most deals die in the thirty minutes between hanging up a Zoom call and opening your inbox. You finish a high-energy discovery call, and by the time you sit down to write the follow-up, the specific pain points the prospect mentioned are already fading. Recording the call on Fathom is a good start, but a transcript sitting in a separate browser tab does not help you draft a reply at the end of the day.

This guide explains how to use Slashy, an AI-native email client built for founders and operators. You stop switching between your recorder and your email to remember what was promised. The goal is a unified environment where your meeting context informs your communication without manual copy-pasting or logging.

Step 1: What the Fathom, Slashy Integration Actually Does

The integration pulls three things out of Fathom and attaches them to the matching calendar event in Slashy: the meeting summary, the transcript, and any action items Fathom captured. They appear in the event detail panel under a Fathom section that expands to the full transcript and the action item list. That is the whole of it, and the narrowness is the point.

The direction is one way. Authorization gives Slashy read access to your meetings, so nothing you do on an event in Slashy writes back to Fathom. Fathom stays the record of what was said; Slashy is where you act on it.

What that changes is where the record lives when you need it. Instead of a transcript in a browser tab you have to go and find, the call sits on the event you are already looking at when you open the thread and start writing. Keeping the record on the event cuts the hunting required to stay on top of several deals at once.

Step 2: Prerequisites Before You Connect

Before you begin the setup, make sure you have the necessary accounts active. You need a Google Workspace or Gmail account, as Slashy operates as a layer on top of Gmail with two-way sync. You also need an active Fathom account that is already recording your meetings.

Have at least one recent recording in Fathom before you connect, so there is something to check against once the link is live. If you are a founder-led sales team, it is worth having your CRM ready too. Slashy connects to CRMs separately, so a HubSpot Gmail integration runs alongside this rather than through it.

Security and permissions are the final check. Slashy is SOC 2 Type II certified and CASA Tier 2 certified, but you will still need to grant OAuth permissions during the setup. Make sure your organization allows third-party integrations with both Google Calendar and Fathom. Slashy uses TLS 1.2+ for data in transit and AES-256 for data at rest to keep your information secure. If you are using a managed workspace, you may need an administrator to approve the Slashy application before it can access your calendar data.

Step 3: Connect Fathom to Slashy via OAuth

The setup is four steps and runs once.

Press Cmd and comma to open Settings.
Choose Integrations in the sidebar, then Meeting Notes, then click Fathom. The meeting-notes tools are grouped together rather than mixed in with the rest, so that is where to look.
Click Connect Fathom and sign in with the Fathom account that records your meetings. Use the right one: if your team records under a shared account, signing in with your personal one connects an empty history.
After Fathom confirms access you are redirected back, and the integration page shows Connected.

Authorization runs through OAuth and grants read access to your meetings. There is no manual sync to run afterwards.

Step 4: Verify the Integration Is Live

Open a past meeting that Fathom recorded and look for the Fathom section in the event detail panel. If it expands to the transcript and the action item list, the connection is doing its job.

The faster check is to ask. Press Cmd and slash and ask the agent something like "What did we agree with Acme last week?". It searches your connected meeting notes and comes back with an inline card showing the meeting, the date, the participants and a link to the recording. If that card appears, the data is reaching the agent, which is what actually matters for drafting.

A connection that is working means your AI email agent is drawing on the call as well as the thread.

Let your inbox handle the calendar

Slashy prepares meetings, shares your availability, and coordinates the next time without another round of messages.

Step 5: What Syncs, and What Doesn't

Understanding the boundaries keeps your workflow clean, and there are two worth knowing.

Matching is by time. Slashy pairs a Fathom recording to a calendar event when both fall in a similar start window. Record a session with no calendar invite and Slashy keeps it in your Fathom list but does not attach it to an event. If a recording lands on the wrong meeting, open the event, click the Fathom section, and reassign it from the dropdown of nearby recordings. The habit that makes this work is booking the call as a calendar event first, which is the same reason turning email into calendar events is worth automating.

The second is what happens when you leave. Open Settings, then Integrations, then Meeting Notes, then Fathom, and click Disconnect, and Slashy stops pulling new recordings AND removes the existing Fathom data from your events. Your data inside Fathom is untouched, but the copy on your calendar goes with the connection.

Data privacy holds throughout this sync. Slashy explicitly states that user data is never used to train AI models, and their AI providers guarantee zero data retention. Your Fathom transcripts are processed to help you write better emails, but they are not contributed to a public LLM. For founders handling sensitive intellectual property or investor discussions, that distinction matters.

Step 6: Act on Meeting Notes Without Leaving Your Inbox

Once the call is on the event, the follow-up stops being a writing job and becomes a request. Ask the agent to draft a reply to that meeting and it works from the action items Fathom captured, alongside your email and your existing memories, in the voice it has learned from your sent mail. If the draft is not quite right, you say what to change in the same plain language you used to ask for it.

Booking the next step runs through the same context, so the meeting you schedule from the thread and the call it came from stay attached rather than living in two places.

After it goes out, follow-up tracking is what stops the thread going quiet. Slashy tracks the threads waiting on a reply, so a deal does not stall purely because nobody remembered to chase it. Writing the follow-up that actually earns a reply is a different job when the specifics of the call are in front of you. If you are also using a CRM like Attio, you might find an Attio email integration useful to make sure these meeting-driven updates are logged for the rest of your team to see.

Conclusion

Recording the call was never the hard part. The gap is between the recording and the reply, and connecting Fathom closes it by putting the summary, the transcript and the action items on the event you are already looking at when you write.

The setup is one connection under Settings, Integrations, Meeting Notes. Slashy starts with 7 days of full access if you want to see what it changes about your follow-up speed.
